This study examines the occurrence, physical characteristics (size, colour, and shape), and polymer compositions of microplastics (MPs) in beach sediments along the Kuala Langat coastline impacted by tourism and fishing activities. Microplastics particle were isolated using density separation, characterized using microscopy and Spectroscopy technique. Microplastic concentrations ranged from 0.01 to 0.21 particles/g in tourist sites and 0.01 to 0.03 particles/g in non-tourist sites, indicating significantly higher MP pollution in tourism-affected areas. The longest MP particle (4951.5 μm) was found in a non-tourist area, while the shortest (84.7 μm) was detected on a tourist beach. Fragment-shaped MPs (82.40 %) were the most dominant, exhibiting a variety of colors and diverse plastic sources. Polypropylene, polyethylene, and polystyrene comprised 80 % of the detected polymers, suggesting that single-use plastics contribute substantially to MP pollution in both sampling sites. These findings provide critical insights for targeted strategies for plastic waste management in tropical coastal areas.
本研究调查了受旅游和渔业活动影响的瓜拉冷岳海岸线海滩沉积物中微塑料的出现情况、物理特征（尺寸、颜色和形状）以及聚合物组成。通过密度分离法分离微塑料颗粒，并用显微镜和光谱技术对其进行表征。旅游景点的微塑料浓度范围为0.01至0.21颗粒/克，非旅游景点为0.01至0.03颗粒/克，这表明受旅游影响地区的微塑料污染明显更高。最长的微塑料颗粒（4951.5微米）出现在非旅游区，而最短的（84.7微米）在旅游海滩被检测到。碎片状微塑料（82.40%）最为常见，呈现出各种颜色和多样的塑料来源。聚丙烯、聚乙烯和聚苯乙烯占检测到的聚合物的80%，这表明一次性塑料在两个采样点的微塑料污染中占很大比例。这些发现为热带沿海地区塑料垃圾管理的针对性策略提供了关键见解。
